Trusted by the world’s leading gold miners

PhotonAssay™ is a non-destructive analytical technique that uses high-energy X-rays to measure the amount of gold, silver, copper and other elements in geological samples. Originally developed through CSIRO research and commercialised by Chrysos Corporation, PhotonAssay™ is deployed at mine sites and commercial laboratories around the world.

Unlike traditional fire assay, which requires crushing, splitting, fluxing, and smelting a 50-gram sub-sample over many hours, PhotonAssay™ analyses the entire 500-gram sample in two minutes. The sample remains intact and can be remeasured or stored for future reference.

The technology eliminates lead-based fluxes and high-temperature furnaces, removing key occupational health hazards and producing zero scope 1 emissions. The result is data that Competent and Qualified Persons trust, regulators accept under JORC and NI 43-101 reporting codes, and that miners around the world are basing decisions on every day.

Chrysos Corporation Ltd (ASX: C79) combines science and software to create technology solutions for the global mining industry.

With staff across the globe, Chrysos’ team of scientists, engineers and industry specialists blends innovation, technical expertise and superior customer service to create cutting-edge assay technologies and services that deliver the crucial operational data customers need to achieve better business outcomes.

Originally developed at Australia’s national science agency, CSIRO, the company’s flagship product PhotonAssay™ delivers faster, safer, more accurate and environmentally-friendly analysis of gold, silver, copper and other elements. The technology has rapidly displaced slower, more hazardous and costly processes to become the mining industry’s most innovative and valuable assaying solution.
